IPC: G01S13/90
Filed: 1988-04-11
Abstract: PURPOSE:To enable normal operation even in an invisible area or regardless of a change in height larger than expected, by detecting a reception timing at each action to generate a transmission pulse repetition frequency (PRF) corresponding to a change in height of a platform. CONSTITUTION:An synthetic aperture radar is provided with a reception timing detector 1, a PRF control section 2 and a transmitting section 3. A reception timing signal outputted from the reception timing detecting section 1 is inputted into a reception timing discriminator section 21 of the PRF control section 2 to be compared with a reception timing corresponding to a height at which a PRF must be changed. A PRF generating section 22 is controlled by the output thereof to output a transmission trigger corresponding to the height of the platform. A transmission pulse is outputted from a transmitter 3 by the transmission trigger.

Abstract: PURPOSE:To reproduce with high accuracy data that correspond to mutual spacing among marks without generating fluctuations, at the time of reproducing data from a recording medium recorded with high density. CONSTITUTION:A reproducing laser beam with an elliptic cross section which is emitted from a semiconductor laser 18 is incident on an objective lens 21 via a collimator lens 19 and a 1/4 wavelength plate 20 and through the objective lens 21 the beam is converged on the pit of the above-mentioned recording medium 16. The converged laser beam is converged as an elliptic beam spot 26 which is long in the longitudinal direction of a recording track while keeping a shape at the time of being emitted from the semiconductor laser 18, at it is. The irradiating area in the longitudinal direction of the recording track of the elliptic beam spot 26 is smaller than the double of the shortest distance between a pair of pits, and larger than the longest distance. By such structure, from an interference pattern obtained by simultaneously irradiating plural marks with the reproducing beam, the highly accurate reproduction is available without the influence of fluctuations.

Title: Manufacture of semiconductor light-receiving device
Inventor: YAMAZAKI SUSUMU
IPC: H01L31/107
Filed: 1982-05-27
Abstract: PURPOSE:To realize the uniform and high multiplication factor of a light-receiving device by a method wherein the depletion layer in the vicinity of a junction is sufficiently widened by joining a P<+> type InP layer and an N<+> type InP layer together, thereby enabling to reduce a dark current. CONSTITUTION:The spreading of a depletion layer is suppressed as compared with the part located directly below the guard ring 9, where no layer 14 exists, by the depletion layer located in the vicinity of the junction between the P<+> type InP layer 21 and the third InP layer 16 located under said layer 21, which is sufficiently spread out due to the layer 16 having N<+> type, thereby enabling to weaken the field strength of the spread part, and also by the existence of the second N<+> type InP layer 14 at the part directly below the layer 21. As a result, the reverse withstand voltage of the layer 21 part is lowered than that of a guard ring 9 part. Accordingly, a low-noise APD having a low dard current and a sufficient multiplication factor can be manufactured easily.

Title: Resist constituting body for forming lithographic pattern
Inventor: IZAWA YOSHIE
IPC: G03F7/20
Filed: 1988-04-13
Abstract: PURPOSE:To improve the effective sensitivity of a photosensitive material by forming a layer contg. a fluorescent material or a fluorescent material layer on the photosensitive material such as resist. CONSTITUTION:The resist 6 is irradiated via a mask pattern 3 and the fluorescent material layer 7 by the X-rays generated from an X-ray source 1. After the fluorescent material 7 is formed on the surface of the resist 6, the pattern is irradiated by the main rays such as X-rays to expose the resist 6. The resist 6 is thus exposed by the main rays of the X-rays and the fluorescent rays emitted from the org. fluorescent material 8. Namely, the rays which project the pattern on the resist 6 are the X-rays and the fluorescent rays play the role of intensifying the effective intensity. The effective sensitivity of the photosensitive material in the lithography for X-rays is thereby increased and the good performance is easily obtd.

Title: Formation of electrostatic image freed of black image
Inventor: HIRATA MASAO
IPC: G03G13/22
Filed: 1979-07-19
Abstract: PURPOSE:To enable an electrostatic image with its black image erased to be easily formed, by forming on a substrate an electrostatic image reverse in polarity corresponding to the black image of an original, and overlaying this image on the other image. CONSTITUTION:Photoconductive photosensitive layer 1A on the outer circumference of photosensitive drum 1 is positively charged, and exposed to the light image from original 5 transmitted through dichroic filter 9, resulting in forming electrostatic positive images corresponding to black image B and red image R, because filter 9 obstructs transmission of red light. On the other hand, photosensitive layer 2A of photosensitive drum 2 is negatively charged, and exposed to the reflected light from filter 9, resulting in forming an electrostatic negative image corresponding to black image B of original 5 on layer 2A because filter 9 functions as a transmitter of the red light. Then, layer 1A of drum 1 and layer 2A of drum 2 are contacted with each other, thus permitting the positive and negative charges of the black image to be neutralized and the electrostatic image corresponding to only red image R to be formed on layer 1A.

IPC: H02P3/18
Filed: 1987-04-15
Abstract: PURPOSE:To brake and stop a lowering load in any case, by using retarding torque due to regenerative braking, together with mechanical braking. CONSTITUTION:At the time of loading negative torque under lowering operation, a first semiconductor switch TR1 is in an ON-state, and an inverter is operated via a thyristor TH3 and a transformer T, and the regenerative braking of a squirrel-cage motor M is performed. In this case, a second semiconductor switch TR2 is kept in an OFF-state, and a load resistor R is disconnected from a circuit. When power interruption occurs under the lowering operation, then the first semiconductor switch TR1 is turned off, and the second semiconductor switch TR2 is turned on, and regenerative energy from the squirrel-cage motor M is consumed by the load resistor R, and regenerative retarding torque is generated. By using the electrical retarding torque together with retarding torque for mechanical braking, a lowering load can be controlled and stopped for emergency, even at a high rotational speed.
